I have a application where I must do a positioning of a conveyor belt with a PF525. The Motor of the conveyor has an incremental encoder.
So our CAD dept decided to use a 25-ENC-1 card in the PF525.

I saw that this card has no connection terminal for the zero pulse of the encoder.
So as I said I want to do a positioning with this application no speed monitoring.

Are there any hints if this is possible with that hardware? If yes a few first steps would be appreciated! Can the drive do the positioning itself or do I need the encoder value in the PLC? How do I get the encoder value to the PLC?

tarik's last link has the details on how I did it - let me know if you need more info.

One thing I will add - as the technote says, the speed parameter is a 32-bit parameter, which chews up two of your precious four datalinks. However it need not be this way under all circumstances. In my application, the encoder was turning quite slowly, and I was able to be quite confident that unless someone decided to run the motor up to several thousand hertz, my value was never going to get so large that it couldn't be represented using only the first 15 bits. So there was no point me wasting a datalink on a parameter that was going to be zero 100% of the time, and I only used the one datalink. Depending on your application, you may be able to do the same. I *think* there may also be a parameter you can play with that effectively adjusts the resolution of your speed feedback, meaning if you did have a higher speed but didn't need the resolution/accuracy, you could get the speed in say 10's of RPMs instead of 0.01's of RPMs, and then scale it in the PLC - the would also help get you in under the 15-bit limit.

Hopefully there's enough data there to get things moving - if not let me know and I'll try to dig out my old files.
